UN 1TB Il FRANK B. WILKINSON, OF HILLMAN, MICHIGAN.

CHIMNEY-LINING.

To all whom t may concern.'

Be it known that I, FRANK B. TimunsoN, a citizen of the United States,residing at Hillman, in the county of Montmorency and State of Michigan,have invented a new and useful Chimney-Lining; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention about to be set forth pertains to a new and useful chimneyor line lining.

The invention in its fundament-al principle aims as its most importantobject to provide an improved device of this character by which chimneysor flues are prevented from becoming overheated, which very often causesfires.

The invention aims as a further object to provide a lining for chimneysor flues having elements by which the said lining is held securely tothe inner surface of the chimney or flue, as will be readily manifest.

The invention directs as a further object to provide flanges upon thelower portion of the lining, which are embedded between the base of theflue or chimney and the flue proper.

A further object of the invention is to provide a lining composed of onepiece of metal and provided with a lapped joint, which is disposed inthe rear of the flue or chimney, as seen clearly in the drawings.

This invention comprises further objects and combinations of elements,which will be hereinafter more fully described, shown in theaccompanying drawings, and the novel features thereof will be pointedout by the appended claims.

The features, elements and the arrangement thereof, which constitute theabove entitled invention, may be changed and varied, that is to say, inan actual reduction to practice, with the understanding that the changesand variations accruing from said reduction to practice are limited tothe scope of the appended claims.

To obtain a full and correct understanding of the details ofconstruction, combinations of features, elements and the advantages,reference is to be had to the hereinafter set forth description and theaccompanying drawings in connection therewith,

wherein- Specification of Letters Patent.

Application led June 16, 1909.

Serial No. 502,442.

Figure l is a vertical section through a chimney or flue, showing thesame provided with the improved lining', of any suitable metal. Fig. 2is a perspective view of the lining removed, embodying the improvedfeatures thereof. F 3 is a transverse section on line Sw of Fig. l.

In regard tothe drawings,wherein similar reference characters indicatecorrespoiuiling parts in the several illustrations, by figures. ldesignates a chimney or tine constructed of any suitable material, thatis to say, the outside portion may be constructed of brick or stone, and2 designates a metallic lining composed of a single piece of metal, andwhich when formed to coincide with the contour of the chimney a lappedjoint 2l is provided, that is to say, the ends of the single piece ofmetal are lapped and are designed to be held together by rivets or othersuitable means 4, as seen in the drawings, the other suitable means, forinstance, may be a tongue or lip 5 struck out of thel metal which isdesigned to engage an aperture t3 of the opposite end of the metal;which tongue or lip being bent, as indicated at T in the drawings, so asto prevent (ilisplacement of the connecting ends of the lining.

The lining is provided with flanges 8, bctween which recesses 9 areformed, as seen clearly in Figs. l and 2 of the drawings. The outercircumference or surface of the lining is provided with a plurality ofelements 10, which are designed to engage the inner circumference of thebrick or stone Hue, so as to prevent displacement of the said lining.The lining is provided with an integral cylindrical portion l2 to whichthe elbow (not shown) of a stove pipe may be connected, but, if desired,in place of the said cylindrical portion, a register 13 may be provided,as seen clearly in Fig. l, while the cylindrical portion is shownclearly in Fig. 2. In utilizing a lining of this character, a suitablebase of masonry, which may be the basement of a house, that is to say, aportion thereof, is constructed, and upon which the flanges of thelining are placed, after which plaster, cement or other matcrial isplaced upon the said `flanges and between the recesses 9, that is tosay, after a layer of plaster, cement or other material is placed uponsaid base. After the recesses 9 and the flanges 8 are provided withplaster, cement or other material, a construction of masonry 15 is builtthereupon and around the said metallic lining, thus allowing theelements 10 to be received by certain joints of the masonry, so as tosecurely hold the lining in place, as seen clearly in Fig. l.

After the masonry is completed around the lining, the projectingportions 16 of 'said flanges are bent, as seen at 17, that is to say, inopposite directions, so as to insure the said lining and the masonryfrom displacement, as will be readily manifest.

From the foregoing, the essential features, elements and the operationof the device, together with the simplicity thereof, will be clearlyapparent.

Having thus fully described the invention, what is claimed as new anduseful, by the protect-ion of Letters Patent, is

1. In a device as set forth, a chimney or flue composed of masonry, alining therefor of a single piece of metal having its free endsconnected to form a lapped joint in the rear of the chimney, said endsforming the lapped joint having a tongue or lip and a recessedconnection for causing said ends to form a secure lapped joint, saidlining being provided with flanges upon its lower portion designed to beembedded within the masonry and having their extreme ends bent inopposite directions, and means for securing the lining to the innersurface of the masonry.

2. In a device as set forth, a chimney or flue composed of masonry, alining therefor of a single piece of metal having its free endsconnected to form a lapped joint in the rear of the chimney, said endsforming the lapped joints having a tongue or lip and a recessedconnection for causing said ends to form a secure lapped joint, saidlining being provided with flanges designed to be embedded within themasonry and having their extreme ends bent in opposite directions, saidflanges having therebetween recesses in which the plaster of the masonryextends, and elements carried by the lining to be embedded in themasonry to securely hold the lining within the chimney.

3. In a device as set forth, a chimney or flue composed of masonry, alining therefor of a single piece of metal having its free ends lappedupon one another, said single piece of metal having upon its extremeedges tongues or projections, and provided with apertures into which thesaid tongues or projections are extended and bent in opposite directionsto securely hold the lapped portions of the metal,together, said liningbeing provided with flanges upon its lower portion designed to beembedded within the masonry and having their extreme ends bent inopposite directions, said lining having between said flanges recessesinto which the cement of the masonry extends, and conical projectionsembedded in the masonry for securing said lining to the inner surface ofthe masonry.

ln testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses. i
